Retinoblastoma: A New Technique for Orbital Exenteration

Abstract

Purpose and Design: Having to remove an invasive Retinoblastoma one aims to avoid an unstable orbital cover after removing the periosteum and when an usual skin graft procedure might not assure the stable support of an ocular prostheses. Methods: Based on de-doubling the lids (skin, tarsus and conjunctiva) as well as moderately freeing the peri-orbital tissues, followed by suturing together the conjunctiva of both lids, Results: purpose and design obtained. Conclusion: A reliable and stable orbital skin cover to support any prostheses Extraperiosteal orbital contents removal is considered essential to avoid a new recurrence when orbital exenteration is required. A new technique for orbital exenteration is described aiming to avoid one unstable free graft on the bare orbital bone that does not usually support the required postoperative aesthetic orbital prostheses.
